Masons Antiques has dated this piece to the 1920s.
An 8 day HAC movement striking the half-hour and the hours.

The medium oak case is nicely polished with a deep, warm patina. The dial glass is convexed and the glazing to the lower half of the case is bevel edged. Keeping perfect time and striking with a crisp clear tone.
A little gem.
All cards accepted.
